In the past several years, there has been an increased usage of smart, always- connected devices at the edge of the network, which provide real-time contextual information with low overhead to optimize processes and improve how companies and individuals interact, work, and live. The efficient management of this huge pool of devices requires runtime moni- toring to identify potential performance bottlenecks and physical defects. Typical solutions, where monitoring data are aggregated in a centralized manner, soon become inefficient, as they are unable to handle the increased load and become single points of failure. In addition, the resource-constrained nature of edge devices calls for low-overhead monitoring systems. In this paper, we propose HLF-Kubed, a blockchain-based, highly available framework for monitoring edge devices, leveraging distributed ledger technology. HLF-Kubed builds upon Kubernetes container orchestrator and HyperLedger Fabric frameworks and implements a smart contract through an external chaincode for resource usage storing and querying. Our experimental results show that our proposed setup forms a low-overhead monitoring solution, with an average of 448 MB of memory and 6.8% CPU usage, while introducing 1.1s end-to- end latency for store operation and 0.6s for ledger querying respectively.

The FabSpace 2.0 project (the open-innovation network for geodata-based innovation - by leveraging Space data in particular, in universities 2.0), funded by European Union under the Horizon Programme, aims at making universities open innovation centres for their region and improving their contribution to the socio-economic and environmental performance of societies. In order to achieve these general objectives, the FabSpace 2.0 project focuses on Earth observation data, an area with high expected socio-economic impact. In this context the universities involved in the project must endorse a new role beyond knowledge providers: co-creators of innovations. This does not mean that they will replace businesses and give up basic research, but that they collaborate with businesses to tackle market challenges and capitalize on opportunities.
